Abstract

The embodiments of the present invention relate to a method for transmitting control information by a base station in a wireless communication system, wherein the method comprises a step of transmitting a physical downlink control channel (PDCCH). The downlink control information of the PDCCH may include an indicator indicating whether or not a reference signal is transmitted in a time domain corresponding to the subframe in which the PDCCH is transmitted.
